Muller*, T.L. de Vries*, B.A. Dippenaar*, and J.C. Vreugdenburg* Synopsis Iron ore fines are agglomerated to produce sinter, which is an important feed material for blast furnaces worldwide.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

A range of iron ores were used in varying proportions to prepare 28 different ore mixtures. Each mixture was classified according to its granulation index and sintered in a pilot plant. The resulting sinters were characterised by chemical analysis, degradation during reduction in the blast furnace (reduction degradation index test), cold strength …

The present investigation deals with the sinterability of Goa (India) iron ore having high Fe (65.2%) content. The sinter basicity (CaO/SiO2) and its MgO were varied in the 2.0 to 2.5 and 1.5 to 3 ...

To prepare sinter mixture, all of the iron ore, fluxes, return fines, and coke breeze are granulated in a drum mixer which is 1000 mm in length and 600 mm in diameter for 5 min. The sinter mixture was loaded into a sintering pot with 900 mm in height, and ignited at 1150 ℃ ± 50 ℃ with suction negative pressure of 5 kPa for 2 min.
